Advanced Science, EarlyView.Collagen type I (Col I) is integrated with self‐assembling peptide RADA16 and loaded with anti‐bacterial peptide SAAP148 to develop a self‐assembled nano‐microstructure hydrogel (Col I‐RADA16‐SAAP148, CRS) without chemical cross‐linkers. CRS exhibits excellent mechanical properties, sustained SAAP148 release to inhibit bacterial infection, macrophage ...

On the 2-token graph of a graph
AKCE International Journal of Graphs and Combinatorics, 2020 Let be a graph and let be a positive integer. Let = and . The -token graph is the graph with vertex set and two vertices and are adjacent if and , where denotes the symmetric difference. In this paper we present several basic results on 2-token graphs.

Discrete Applied Mathematics, 2002 A chordally signed graph is defined as a signed chordal graph (each edge is designated as being positive or negative and every induced cycle is a triangle) in which every cycle \(C\) containing an even number of negative edges (positive cycles) has a chord \(e\) such that \(C\cup\{e\}\) forms two positive cycles.

Advanced Intelligent Systems, EarlyView.Worklow for calibrating excursion sets of random fields using methods from generative artificial intelligence. This article presents a computational method for generating virtual 3D morphologies of functional materials using low‐parametric stochastic geometry models, that is, digital twins, calibrated with 2D microscopy images.

Vertex partitions of chordal graphs [PDF]
Journal of Graph Theory, 2006 AbstractA k‐tree is a chordal graph with no (k + 2)‐clique. An ℓ‐tree‐partition of a graph G is a vertex partition of G into ‘bags,’ such that contracting each bag to a single vertex gives an ℓ‐tree (after deleting loops and replacing parallel edges by a single edge).

Mineralized area of the human rib cross‐sections from early puberty until adulthood
The Anatomical Record, EarlyView.Abstract Ribs undergo numerous changes during growth and development. Although they occur both externally and internally, the latter are not as extensively documented during the transition from puberty to adulthood. Therefore, it is unknown how rib cross‐sectional mineralized area changes during this period.

A graph is locally chordal if, locally at each vertex, it is chordal, i.e. composed of cliques glued along a tree. In addition to extending many classic characterizations of chordal graphs, we show that locally chordal graphs are precisely those graphs $G$ which can be decomposed into cliques arranged in the shape of a high-girth graph.

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs
Communications on Pure and Applied Mathematics, EarlyView.Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure

Developmental Dynamics, EarlyView.Abstract Background Midline establishment is a fundamental process during early embryogenesis for Bilaterians. Midline morphogenesis in non‐amniotes can occur without mitosis, through Planar Cell Polarity (PCP) signaling. By contrast, amniotes utilize both cellular processes for developing the early midline landmark, the primitive streak (PS).
